通过在板栗上接种菌根真菌 ,证明几种真菌能与板栗形成不同共生程度的菌根 ,菌根对板栗幼苗生长有不同程度的促进作用 以Rhizopogensp .和Lycoperdonfuscum对菌根苗株高和地径的促进作用大 ,土壤灭菌后接种效果明显优于未灭菌的处理 具有菌根的板栗幼苗在PEG脱水处理后 ,暂时萎蔫出现晚 ,萎蔫系数小 ;菌根苗的细胞膜透性和SOD酶活性相对低 菌根的存在可显著地提高幼苗对干旱胁迫的抗性
Mycorrhizal fungi were inoculated on the chestnut, which proved that several fungi could form mycorrhizae with different symbiosis with the chestnut. Mycorrhiza promoted the growth of chestnut seedlings to varying degrees. The effects of Rhizopogensp. And Lycoperdonfuscum on the plant height and diameter The effect of inoculation after soil sterilization was better than that of non-sterilized treatment. The chestnut seedlings with mycorrhizal had a little wilt after watertreatment of PEG, the coefficient of wilting was small and the membrane permeability and SOD activity of mycorrhizal seedlings were relative The presence of low mycorrhizal can significantly improve seedling resistance to drought stress
